[0029] The strong electromagnet 5 is completely adhered to the wall surface of the distribution box in a flat mode, so that the adsorption and fixing performance of the strong electromagnet 5 on the distribution box is improved, the distribution box can be transferred from the outside of the first ground rail assembly 1 to the distribution box frame 2 on the inside of the first ground rail assembly 1, and the distribution box can also be transferred from the distribution box frame 2 to the outside of the first ground rail assembly 1.

[0030] The operation process of the mechanical arm 3 is controlled by a PLC program.

[0031] In the example, the distribution box is divided into two areas, i.e., an upper compartment and a lower compartment, by a layered plate.

[0032] Specifically, a support plate 8 for bearing the distribution box is arranged on the top of the distribution box frame 2, positioning assemblies 9 are symmetrically arranged on the two sides of the support plate 8, the distribution box transferred to the support plate 8 is adjusted in position through the positioning assemblies 9, and the distribution box is positioned and fixed.

[0033] Specifically, a support plate 8 for bearing the distribution box is arranged on the top of the distribution box frame 2, positioning assemblies 9 are symmetrically arranged on the two sides of the support plate 8, the distribution box transferred to the support plate 8 is adjusted in position through the positioning assemblies 9, and the distribution box is positioned and fixed.

[0034] The positioning assembly 9 comprises a support block 11 fixedly installed on the side wall of the support frame 10, a first motor 12 fixedly installed at the middle region of the support block 11, a bearing rod 13 fixedly installed on the side wall of the first motor 12 and having an output end upward, an extension rod 14 fixedly installed on the side wall of the bearing rod 13, the extension rod 14 being a hollow structure, the end of the extension rod 14 being connected with the outside environment and the internal hollow structure, three sliding short rails 15 fixedly installed on the internal side wall of the extension rod 14, a support rod 16 slidably connected with the three sliding short rails 15, the end of the support rod 16 being a flat surface, and a plurality of first micro pressure sensors 19 evenly and densely arranged at the end of the support rod 16, the first micro pressure sensors 19 being used to generate data under pressure and transmit the data to the PLC system;

[0035] After the distribution box is transferred to the top surface of the support plate 8, the first motor 12 is controlled to rotate by the PLC program, the bearing rod 13 is driven to rotate, then the extension rod 14 is driven to rotate to a position perpendicular to the support plate 8, then the extension rod 14 is driven to extend, and the end surface of the extension rod 14 is tightly attached to the outer wall surface of the distribution box, the four extension rods 14 around the distribution box are simultaneously operated, and then the position of the distribution box is corrected, so that the distribution box is in the preset forward position, and the detection result of the distribution box is avoided to be incorrect due to the inclined distribution box;

[0036] After the operation of the four extension rods 14 is completed, the support rod 16 is controlled to move outward along the sliding short rail 15 by the PLC program, and then the first micro pressure sensor 19 is tightly attached to the outer side wall surface of the distribution box, if all the first micro pressure sensors 19 can generate data, it indicates that the connection position of the extension rod 14 and the distribution box is correct, and the distribution box can be accurately limited and fixed, if one or more of the first micro pressure sensors 19 cannot generate data, it indicates that the connection of the extension rod 14 and the distribution box is not perpendicular, if the distribution box is limited and fixed in this state, the surface of the distribution box will be worn, the support rod 16 continues to maintain the state of pressing the distribution box after detecting whether the distribution box is correctly corrected, and plays a further limiting and fixing role on the distribution box;

[0037] During the position correction of the four extension rods 14 on one distribution box, the extension rod 14 will match the position movement of the distribution box to generate rotation, and the rotation process is realized by taking the output end of the first motor 12 as a rotating rod through the bearing rod 13, at this time, the first motor 12 is in a passive operation state, if the bearing rod 13 is set as a fixed structure, the distribution box will be damaged during the correction of the four extension rods 14 on the distribution box;

[0038] A rubber layer is arranged on the end wall surface of the extension rod 14, which plays a buffering role during the limiting and fixing of the distribution box;

[0040] Wherein, the telescopic rod 14 is a prior art structure, and the inside of the telescopic rod 14 is configured with a power supply.

[0041] Specifically, the second ground rail assembly 20 is arranged between the first ground rail assembly 1 and the distribution box frame 2, the base 21 is slidingly connected on the second ground rail assembly 20, the top of the base 21 is fixedly installed with the top rail 22, three metal plates 23 are slidingly connected on the top rail 22, the side wall of the metal plate 23 towards the distribution box frame 2 is fixedly installed with the vertical rail 24, the sliding block 25 is slidingly connected on the vertical rail 24, the side wall of the sliding block 25 is fixedly installed with the second motor 26, the output end of the second motor 26 is fixedly installed with the disc 27, the side wall of the disc 27 is fixedly installed with the side rail 33, two detection plates 28 are slidingly installed on the side rail 33, a plurality of spring rods 29 are uniformly arranged on the opposite faces of the two detection plates 28, the end of the spring rod 29 is fixedly installed with the clamping plate 30, and the spring rod 29 has a certain buffering function to protect the layered plate to a certain extent.

[0042] Wherein, the detection plate 28 has a telescopic function, and a plurality of second micro pressure sensors 32 are uniformly arranged on the two side walls thereof, and the second micro pressure sensor 32 functions to generate data under pressure and transmit the data to the PLC system.

[0043] Wherein, after confirming that the position of the distribution box has been corrected, the third driving element 31 driving the base 21 drives the base 21 to move along the second ground rail assembly 20, drives the three metal plates 23 to move in turn in front of the distribution box, and detects the same, and after the detection is completed, moves to the next distribution box for detection. During this period, the mechanical arm 3 transfers the distribution box that has been detected out, and replaces the next distribution box, the mechanical arm 3 and the detection plate 28 alternately process the distribution box at the same time, which improves the detection speed of the distribution box. Compared with the previous sampling detection, this assembly line detection can realize one-by-one detection, so that the detection accuracy of the distribution box is significantly improved.

[0044] Wherein, the distribution box is detected for internal edge gap, layered plate firmness, and layered plate strength.

[0045] The inner edge gap detection: confirm the distribution box position is accurate, drive the two sides of the metal plate 23 to the middle of the metal plate 23, so that the two sides of the metal plate 23 are moved to the inside of the warehouse area in the distribution box, then drive the slider 25 on the two sides of the metal plate 23 to move to the upper warehouse area of the distribution box, then drive the second motor 26 on the two sides of the metal plate 23 to operate to drive the disc 27 to rotate, finally drive the two detection plates 28 on the frame to be in the state of alignment, in this embodiment, the two detection plates 28 are vertically distributed in the state of alignment, after confirming that the two detection plates 28 are in the state of alignment, drive the detection plate 28 to extend until the end of the detection plate 28 is close to the inner side wall of the distribution box, then drive the two sides of the metal plate 23 to move towards the two sides along the top rail 22, until the detection plate 28 extending into the upper warehouse area of the distribution box moves close to the side wall of the upper warehouse area of the distribution box, then drive the slider 25 to move up and down along the vertical rail 24, drive the detection plate 28 close to the side wall of the upper warehouse area of the distribution box to move up and down, if the second micro pressure sensor 32 continuously generates data during the up and down movement, it indicates that the side wall of the upper warehouse area of the distribution box is not curved, if the second micro pressure sensor 32 intermittently generates data during the up and down movement, it indicates that the side wall of the upper warehouse area of the distribution box is curved, mark the problem of this distribution box in the PLC system, and process it again later.

[0046] After the detection of the upper warehouse area of the distribution box is completed, repeat the above operation to detect the lower warehouse area of the distribution box.

[0047] The layered plate firmness detection: confirm the distribution box position is accurate, drive the middle metal plate 23 to the middle position of the support plate 8, at this time drive the slider 25 to move to the front area of the layered plate along the vertical rail 24, at this time drive the two detection plates 28 to move outward along the side rail 33, so that the distance between the two detection plates 28 is maximized, then drive the two detection plates 28 to extend, until the two detection plates 28 are respectively on the upper and lower sides of the layered plate, then drive the two detection plates 28 to move towards each other along the side rail 33, until the clamping plate 30 is close to the layered plate, thus the linear two detection plates 28 clamp and fix the layered plate process, finally drive the slider 25 to move up and down along the vertical rail 24 to detect the layered plate for the first time, after the first firmness detection, drive the two detection plates 28 clamping and fixing the layered plate to retract and pull the layered plate, and detect the layered plate for the second time;

[0048] The first firmness detection is to detect whether the layered board shakes after being installed in the distribution box. If the layered board breaks or shakes widely, the resistance to the up-and-down movement of the detection plate 28 changes, and the PLC system is marked. The second firmness detection is to detect whether the layered board is easy to fall off after being installed in the distribution box. If the layered board falls off the distribution box, the resistance to the inward movement of the detection plate 28 changes, and the PLC system is marked.

[0049] The up-and-down movement distance of the detection plate 28 is preset in the PLC system, and the inward movement distance of the detection plate 28 is also preset in the PLC system.

[0050] The layered board strength detection: three metal plates 23 move simultaneously and are clamped and fixed at three equal parts to achieve clamping and fixing of the layered board. The detection plate 28 of the three metal plates 23 clamps and fixes the layered board. The three metal plates 23 move up and down simultaneously to perform the first strength detection on the layered board. After the first strength detection is completed, the detection plate 28 matched with the middle metal plate 23 does not move, the detection plate 28 matched with the left metal plate 23 moves upward, and the detection plate 28 matched with the right metal plate 23 moves downward to perform the second strength detection on the layered board.

[0051] The first strength detection and the second strength detection are both to detect the strength of the layered board. If the layered board breaks, the resistance to the up-and-down movement of the detection plate 28 changes, and the PLC system is marked.

[0052] The up-and-down movement distance of the detection plate 28 in the first strength detection and the second strength detection is preset in the PLC system.

[0053] After the above three detection processes, manual inspection is required once to mainly check whether the layered board is broken. The above three detections achieve comprehensive coverage detection of the inner layer of the distribution box, eliminate the detection blind area, improve the comprehensiveness and accuracy of the detection, and secondly, the application of the automatic control module makes the detection process more efficient and convenient, reduces manual operation, reduces human error, and improves detection efficiency. In addition, the PLC system automatically marks unqualified distribution boxes, provides strong support for maintenance work, and reduces the difficulty and cost of maintenance.
